There are some Symbian applications I couldn’t live without, and some that I really enjoy using it on my (old by now) Nokia 6680.

Symbian OGGPlay – the audio player that helps me better manage my 1 GB memory card and turn my phone in a real portable player. It plays MP3, OGG, AAC and MP4 files, it recognizes Winamp playlists and has a skinnable interface.

FExplorer – is another utility that has better functions, a better interface and is much fastr than the phone’s file manager. Plus it lets you explore all the files, including the temp and OS’s folders.

TaskSpy – is a task manager for Symbian OS devices. It allows you to get more control and information over running tasks on your mobile phone. You can quickly switch tasks, kill processes and threads or free unused memory, as well as display detailed information about system resources. Other features, such as tracking cpu load and free memory, though aimed to developers, may result of interest to advanced users. You will be surprised to see how many applications are remaining resident in phone memory after (you think) you close them.

AutoLock – is an automatic key lock application for S60. It starts automatically when the phone is turned on, it has a Setup tool to change inactivity time and it’s running completely at the background. The fact that Nokia didn’t include this as a default feature it still amazes me.

ShoZu – is the easiest way to upload photos and videos to your sharing Web site. With just one click your photo or video is on the Web. It supports a wide range of webservices (from flickr to youtube) and weblogging systems (Blogger, Typepad, WordPress). You never have to worry about syncronizing the pictures you take, the movies you shoot or the agenda with your computer. They will be online by the time you get home.

YahooGo! – brings the internet to your mobile, starting with a push email (for your yahoo account), calendar and agenda sync, news, yahoo messenger, yahoo local or yahoo search.

Opera Mobile – is the fastest, most secure browser available for S60 and Windows mobile handsets.

GMail Mobile Java Client – if you really need all your Gmail features right on your cell then download the java client google developed.
